Isopropyl Alcohol

Isopropyl Alcohol (IPA) 99% is essential in offset printing for its multifaceted roles, including reducing the surface tension of the dampening solution, acting as a coolant, and stabilising the ink-water balance. It enhances the wetting of rollers and printing plates, promoting a thin and even water film, and aids in producing clean, consistent print results. Despite its benefits, IPA introduces some challenges, such as contributing to global warming, being flammable, and being costly.

Key Benefits:
  • Reduces surface tension for better wetting of rollers and printing plates.
  • Acts as a coolant, removing heat from critical press components.
  • Stabilises the ink-water balance for consistent and high-quality printing.
